Relay Control Configuration - Equinox Systems ISPnano IV-ATE Series Hardware User Manual

5.0 Relay Control Configuration

The relays on the 'I/O Connector Module' are controlled by the programmer by default. The relays
are automatically energised whenever a programming operation commences and remain energised
until the programming operation is completed. This is the preferred setup as it means that the
programmer is only ever connected to the DUT when in programming mode. It is disconnected from
the DUT at all other times.
On 'ISPnano Series IV ATE' programmer hardware V1.1 and above, it is possible to control the
relays from a 'Remote System' e.g. an external ATE or PLC. This could be useful if the relay
switching is to be coordinated with other operations within the scope of a more complex test /
programming fixture.
The illustration below shows the location of the 'Relay control' link underneath the 'I/O connector
Module':
The control of the relays is set using the solder link BL1 as detailed in the table below.
